Abstract
A marine engine is constructed having an improved component layout so as to reduce the size of the engine even when multiple fuel injectors are employed per cylinder. In one mode, this advantage is accomplished while shielding the fuel injectors from water that may enter through an access opening above the engine. The fuel injectors are also desirably arranged to reduce thermal effects on the fuel injectors by remotely positioning the fuel injectors relative to the engine's exhaust system. In one form, the fuel injectors are mounted on a lower surface of an inclined cylinder and the exhaust pipe is connected to an upper surface of the cylinder for these purposes.
